Description

[Detailed description of the invention] A. Industrial application field This invention is a central cleaner that is constructed by connecting a vacuum cleaner body installed under the floor etc. and a hose outlet provided indoors through piping members and electrical wiring. This relates to the structure of the hose outlet.

B. Prior Art Conventionally, in this type of central cleaner, a hose outlet installed indoors is opened and closed by a rotatable hose outlet cover provided on a hose outlet base. Furthermore, since the pivot shaft of this cover is attached to the hose outlet base using a separate fixture, there are many parts, which has disadvantages such as poor assembly and high cost. .

C. Purpose of the invention The purpose of the invention is to reduce the number of parts in the hose insertion structure of a central cleaner and improve assembly efficiency.

D. Structure of the invention The present invention is a central cleaner in which a vacuum cleaner body installed under the floor etc. and a hose outlet provided indoors are connected via piping members and electrical wiring, and an opening provided in the indoor wall surface etc. A hose socket base mounted to cover the hose socket and a hose socket cylinder body inserted into the opening are installed facing each other, and a hose socket cover is rotated on the hose socket base. The bearing of the cover is inserted into the back surface of the hose socket base from the lower opening of the hose socket base, and the pivot shaft provided on the bearing is inserted into the hose socket base. and a part of the hose insertion tube body.

E. Embodiments of the invention Hereinafter, embodiments of the invention shown in the drawings will be described.

Reference numeral 1 denotes a vacuum cleaner main body installed under the floor or the like, and the main body is connected to hose insertion ports 5, 5 attached to walls 4, 4 of each room via piping members 2 and electric wiring 3. When a hose part 6 with a remote control switch (not shown) of the vacuum cleaner main body 1 is inserted into the hose insertion port 5 and the switch is turned on, the vacuum cleaner main body 1 is operated, and its suction power is transferred to the piping member 2. The hose is connected to the hose insertion port 5 through the hose for cleaning the room.

The hose insertion port 5 includes a hose insertion port base 9 that covers an opening 7 provided in the wall surface 4 from the indoor side and is screwed to a mounting tree 8 located on the back side of the wall surface 4, and 7 and fixed to the back surface of the base 9 with screws 10;
1, and at the inner end of the cylinder body 11 is a hose portion 6 for wiring for remotely controlling the vacuum cleaner body 1.
An annular packing 14 for preventing air leakage which fits into the joint contact piece 12 of the hose section 6 and the piping joint 13 is attached with a screw 16 via a packing holding fitting 15. Further, a hook portion 18 is formed on the upper inner surface of the hose insertion port cylindrical body 11 and engages with a hose hook 17 provided on the hose portion 6 to prevent the hose from coming off.
The outer open end of the hose outlet cylinder 11 is normally covered by a hose outlet cover 19 when not in use,
A cover gasket 21 attached via a seat plate 20 seals to prevent air leakage.

A lower opening 22 is formed in the lower part of the hose outlet base 9 through which the hose outlet cover 19 is inserted from the back side to the front side. Grooves 23, 23 for holding the pivot shaft are formed on both sides.

The hose insertion port cover 19 has bearings 26, 26 formed on both sides of the lower part of the back surface, and the bearings 26, 2
6 is equipped with a pin 25 that serves as a pivot shaft, and both ends of the pin 25 are rotatably accommodated in the grooves 23, 23, and the grooves 23, 23 and the lower part of the hose insertion port cylindrical body 11 are connected to each other. It is held by pin holding parts 24, 24 formed in the. The pin 25 is supported by the grooves 23, 23 of the hose socket base 9 and the pin holding parts 24, 24 of the hose socket cylinder 11, so that it does not come off in the left-right direction or the front-back direction. The rotation of the hose insertion port cover 19 is always performed reliably.

27 is a pin 25 between the bearings 26, 26.
A coil spring is wound around the hose outlet cover 19 to apply a force to always rotate the hose outlet cover 19 in the closing direction.

Reference numeral 28 denotes a control board arranged in parallel on the upper part of the hose insertion tube body 11, and this board is equipped with an operation indicator lamp 29 of the cleaner main body 1 and a dust disposal indicator lamp 30 that warns when it is time to dispose of dust, and screws 31, 31 to the hose insertion port base 9. Further, the lead wires 32, 32 of the control board 28 are connected to the protrusion 34 on the back side of the finger hole 33 formed in the hose insertion port base 9 and the lead wire presser 3 formed on the upper part of the hose insertion port cylinder 11.
5, and is connected to the wiring from the cleaner body 1 through an opening 7 provided in the wall surface 4. 3
Reference numeral 6 denotes a lead wire for the remote control, which is connected to the wiring extending from the vacuum cleaner main body 1.

F. Effects of the invention According to the invention, since the pivot shaft of the hose socket cover is held between the hose socket base and a part of the hose socket cylinder, the swing shaft can be configured easily. The central cleaner's hose plug has high practical value, as it can be attached to the hose socket base without the need for new parts, reduces the number of parts used, and simplifies assembly work. Mouth structure can be obtained.
